For a few people, Dark Sky is going to be the most useful weather app ever

As an Englishman, I know all about rain. I’m intimate with sleet, drizzle, and driving rain both horizontal and vertical. I know about rain that slowly soaks you even though it seems that none is falling, about freezing rain that stings as hard as hail, about the rain that seems to ignore your umbrella and creep into even the best-sealed seams of your clothes.

Other countries might have spectacular monsoons, or driving rainstorms that flow for days, but for variety and ubiquity of precipitation, it’s hard to beat the British Isles. Which is why I’m sad that Dark Sky — an app that predicts the rain forecast for the next hour only — currently only works in the continental United States.
